A Gis Look At Woody Plant Encroachment (Wpe): Mapping Grassland Degradation Through Habitat Succession, Brandon M. Wolf Jan 2023

A Gis Look At Woody Plant Encroachment (Wpe): Mapping Grassland Degradation Through Habitat Succession, Brandon M. Wolf

Geography and the Environment: Graduate Student Capstones

The grasslands of North America remain at a fraction of their historic range. Estimates of acreage remaining vary between 4% and 13%. Affectionately known as the Great Plains, these grasslands have been converted for agriculture, rangeland, infrastructure, and civilization itself. Woody Plant Encroachment (WPE) on the grasslands is a silent, often overlooked, serious threat. The use of a simple GIS can estimate current acreage of a grassland, its adjacent woodland corridor, riparian buffers, and predict future acreage based on trends and hypothetical management scenarios, or lack thereof. The American prairie, though a remnant of its former self, is still home …

Exploring Inequality At Copan, Honduras: A 2d And 3d Geospatial Comparison Of Household Wealth, Heather Richards-Rissetto Jan 2023

Exploring Inequality At Copan, Honduras: A 2d And 3d Geospatial Comparison Of Household Wealth, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

The archaeological site of Copan was a cultural and commercial crossroads at the southeastern Maya frontier. Research indicates that the demographics and sociopolitical circumstances of the city of Copan and its location within a circumscribed pocket (24 km2) of the larger Copan Valley varied through time. These circumstances not only influenced its social, political, and economic interactions, but likely the size, construction, and organization of households, specifically plazuelas. Copan’s plazuelas differ from those located in other Maya regions because they often have smaller house platforms, comprise more than a single patio, and exhibit a larger than normal …

The Rhino Horn Trade And Radical Inequality As Environmental Conflict, Elizabeth Lunstrum, Nícia Givá, Francis Massé, Filipe Mate, Paulo Lopes Jose Jan 2023

The Rhino Horn Trade And Radical Inequality As Environmental Conflict, Elizabeth Lunstrum, Nícia Givá, Francis Massé, Filipe Mate, Paulo Lopes Jose

Global Studies Faculty Publications and Presentations

The illegal wildlife trade (IWT) is one of the most acute global conservation challenges. This paper examines what is driving young men to enter the rhino horn trade while advancing theory on environmental conflict. We show how the illicit rhino horn economy is a telling instance of environmental conflict—largely between ground-level hunters and increasingly militarized state conservation forces—that emerges from a context of radical inequality. We examine how practices ranging from labor migration and sidelining rural development to biodiversity conservation itself have profoundly transformed the Mozambican-South African borderlands from which many hunters originate, in turn generating poverty, exclusion, and vulnerability …

Ethnic Difference At The Center Of Land Struggles In The Americas: A Complex History Of Marginalization And Multidimensional Challenges Among The Garifuna In The Northern Honduras, Kaitlyn Bellamy, Victoria Garcia, Saleh Ahmed, Adriana Archila Jan 2023

Ethnic Difference At The Center Of Land Struggles In The Americas: A Complex History Of Marginalization And Multidimensional Challenges Among The Garifuna In The Northern Honduras, Kaitlyn Bellamy, Victoria Garcia, Saleh Ahmed, Adriana Archila

Global Studies Faculty Publications and Presentations

Across the world, natural resources play a critical role in shaping livelihoods among the ethnic and indigenous communities. This article highlights the struggles Garifuna in northern Honduras face regarding land ownership, despite being constitutionally recognized yet ignored by the government. For them, land struggles are also their racial struggles. Contested land ownerships are the outcomes of historical discriminations, leaving Garifuna vulnerable to violence. This article addresses the multidimensional aspects of land-based struggles that have resulted in social, cultural, and environmental damage, creating insurmountable pressures on local Garifuna livelihoods.

Adaptation Outcomes In Climate-Vulnerable Locations: Understanding How Short-Term Climate Actions Exacerbated Existing Gender Inequities In Coastal Bangladesh, Saleh Ahmed, Elizabeth Eklund, Elizabeth Kiester Jan 2023

Adaptation Outcomes In Climate-Vulnerable Locations: Understanding How Short-Term Climate Actions Exacerbated Existing Gender Inequities In Coastal Bangladesh, Saleh Ahmed, Elizabeth Eklund, Elizabeth Kiester

Global Studies Faculty Publications and Presentations

Adverse climate impacts present a significant challenge for the majority of the world’s population. It is especially true for smallholder farmers in coastal Bangladesh, where some adaptation initiatives appeared to be short-sighted and reproduced further inequity, poverty, and food insecurity. Based on empirical insights, this paper shows how short-sighted climate responses can adversely affect gender equity, illustrated through three adaptation strategies. First, agricultural institutions have traditionally and historically linked with gender roles. Outmigration from the region is gendered as males leave first. This forces increased household and farm responsibilities onto female household members and increased vulnerability. This gendered vulnerability becomes …

To The Cosmos And Back: Modelling Ritualized Movement And Natural Sanctuaries Around The Manialtepec Lagoon, Sami Savateri Jan 2023

To The Cosmos And Back: Modelling Ritualized Movement And Natural Sanctuaries Around The Manialtepec Lagoon, Sami Savateri

Electronic Theses and Dissertations, 2020-2023

Depictions of movement in Late Postclassic and early Colonial Mesoamerican art, maps, and documents show a multi-faceted conception of movement as not only a means of physical travel through the landscape of the mundane world, but also a means to reach the cosmic realms of divine forces. In this thesis, I explored the intersection of movement and ritual in Late Postclassic Oaxaca by modelling a hypothetical ritual circuit around the Manialtepec Lagoon: a bioluminescent lagoon near Oaxaca's Pacific Coast that is significant in oral histories of the Indigenous Chatinos. The Manialtepec Basin lacks the level of continuous occupation or historic …

Using Gis To Better Understand The Cracker Community Of Pat's Island In The Ocala National Forest, Florida, Nicholas Kopp Jan 2023

Using Gis To Better Understand The Cracker Community Of Pat's Island In The Ocala National Forest, Florida, Nicholas Kopp

Electronic Theses and Dissertations, 2020-2023

This research uses GIS methods to contextualize a Florida Cracker community in the Ocala National Forest. My case study is drawn from two seasons of fieldwork and supporting desktop surveys associated with Pat's Island, the home of multiple Cracker families. Cracker culture is historically categorized by its efforts to avoid modernization and prevent the commercialization of traditional lifeways in the quickly shifting society of late-19th and early 20th-century Florida. The geospatial expressions of these Cracker values are an emphasis on semi-remote living, adaptations to a unique environmental context, and the development of a semi-self-sufficient community. This research evaluates how GIS …

Dispossessed Again: Paiute Land Allotments In The Mono Basin, 1907-1929, Robert B. Marks Jan 2023

Dispossessed Again: Paiute Land Allotments In The Mono Basin, 1907-1929, Robert B. Marks

Eastern Sierra History Journal

Like most California Indians, the Kutzadikaa people in the Mono Basin on the east side of the Sierra Nevada Mountains were dispossessed of their land in the second half of the nineteenth century. However, they were not then removed to a reservation. They were left landless with no rights to reclaim their land until the Dawes Act (1887) made land allotments to non-reservation Indians possible. This article explores the history of land allotments in the Mono Basin, and places that story into the broader context of U.S. assimilationist policies but more importantly into the context of local history. Kutzadika …

Evaluation Of Low-Cost Radiometer For Surface Reflectance Re-Trieval And Orbital Sensor’S Validation, Dinithi Siriwardana Pathiranage Jan 2023

Evaluation Of Low-Cost Radiometer For Surface Reflectance Re-Trieval And Orbital Sensor’S Validation, Dinithi Siriwardana Pathiranage

Electronic Theses and Dissertations

This paper evaluates the Arable Mark 2 sensor, an automated and low-cost radiometer, for its potential to retrieve surface reflectance data and validate orbital sensors such as the Landsat-8 (L8) Operational Land Imager (OLI) Level 2 product. While orbital sensors are widely used for monitoring solar radiation changes, managing natural resources, and understanding climatic trends, atmospheric effects can make it challenging to obtain accurate measurements. Equipped with multiple sensors, including long-wave and short-wave radiometers, the Arable Mark 2 sensor can measure upwelling and downwelling irradiance to calculate surface reflectance. To assess the accuracy and consistency of the Arable Mark 2 …

Extended Cross-Referenced Analysis Using Data From The Landsat 8 And 9 Underfly Event, Garrison Gross Jan 2023

Extended Cross-Referenced Analysis Using Data From The Landsat 8 And 9 Underfly Event, Garrison Gross

Electronic Theses and Dissertations

The Landsat 8 and 9 Underfly Event occurred in November 2021, where Landsat 9 flew beneath Landsat 8 in the final stages before settling in its final orbiting path. An analysis was performed on the images taken during this event, which resulted in a cross-referenced with uncertainties estimated to be less than 0.5%. This level of precision was due in part to the near-identical sensors aboard each instrument as well as the underfly event itself, which allowed the sensors to take nearly the exact same image at nearly the exact same time. This initial calibration was applied before the end …

“For Posterity, It’S Something Important To Do”: Festivals, Digital Practices, And Conserving Community Heritage, Enya Moore Dr. Jan 2023

“For Posterity, It’S Something Important To Do”: Festivals, Digital Practices, And Conserving Community Heritage, Enya Moore Dr.

Presentations

This presentation highlights the importance of preserving arts festival activities and uses empirical evidence to underline the significance of the digital turn for archiving this kind of intangible heritage. As Del Barrio et al (2012, pp. 235) argue, cultural festivals are an emblematic example of immaterial cultural heritage, 'since they are experience goods which expire at the moment they are produced and not only express artistic innovations in the field but also draw on previous cultural background, perceived as accumulated cultural capital’ . Data gathered through qualitative fieldwork with rural festival makers are used to explore the potential that digitising …

Migrant-Activist Evidentiary Practices In The Aegean Sea, Beatrice A. Abbott Jan 2023

Migrant-Activist Evidentiary Practices In The Aegean Sea, Beatrice A. Abbott

Theses and Dissertations--Geography

This project examines digital maps and images made by migrants and activists traversing or helping others to traverse the Greek-Turkish maritime border in 2015 and early 2016, when over a million people arrived to European shores, mostly by way of the Aegean Sea. These maps were made using applications such as Google Maps, Bing Maps, Maps.me, and WhatsApp and circulated on public Facebook groups and pages. Through a visual analysis of these digital artifacts, I look at how they can be read to witness and contest deadly border geographies produced through migratory policies and practices of deterrence. Further, I argue …

Hoarding Lifesaving Knowledge While Millions Die: The Political Economy Of Global Covid-19 Vaccine Apartheid, Kenneth Stancil Jan 2023

Hoarding Lifesaving Knowledge While Millions Die: The Political Economy Of Global Covid-19 Vaccine Apartheid, Kenneth Stancil

Theses and Dissertations--Geography

Coronavirus vaccines saved millions of lives, but experts estimate that the suboptimal production and inequitable distribution of shots resulted in nearly 3 million preventable Covid-19 deaths in 2021 and 2022 as well as millions of indirect deaths during the pandemic. These avoidable fatalities are inseparable from the grotesquely unequal vaccination rates between rich and poor nations. Dose hoarding by high-income countries contributed to vaccine inequality, but the “vaccine apartheid” inflicted on low-income countries reflects an even more fundamental injustice: knowledge hoarding by profit-maximizing pharmaceutical corporations—aided and abetted by wealthy governments—which deprived generic manufacturers of the right to produce additional lifesaving …

Impact Of Atmospheric Correction On Classification And Quantification Of Seagrass Density From Worldview-2 Imagery, Victoria J. Hill, Richard C. Zimmerman, Paul Bissett, David Kohler, Blake Schaeffer, Megan Coffer, Jiang Li, Kazi Aminul Islam

OES Faculty Publications

Mapping the seagrass distribution and density in the underwater landscape can improve global Blue Carbon estimates. However, atmospheric absorption and scattering introduce errors in space-based sensors’ retrieval of sea surface reflectance, affecting seagrass presence, density, and above-ground carbon (AGCseagrass) estimates. This study assessed atmospheric correction’s impact on mapping seagrass using WorldView-2 satellite imagery from Saint Joseph Bay, Saint George Sound, and Keaton Beach in Florida, USA. Coincident in situ measurements of water-leaving radiance (Lw), optical properties, and seagrass leaf area index (LAI) were collected. Seagrass classification and the retrieval of LAI were compared after empirical line …
